4 Claims.

This invention relates in general to improvements in water closets and has more particular reference to the type of water closet in use in vehicles.

A principal object of the invention is the provision of a water closet adapted for use in moving vehicles of lighter construction where a savings in weight is desired, as in the case of the new type construction of streamline trains, busses and trailers.

An important object of the invention is the provision of a water closet for vehicles which is much more simple in structure and more easily adapted for assemblage than those of the prior art.

Heretofore, it has been found necessary to construct the water closets for railways, trailers, busses and the likein several pieces which are then assembled. The assembled unit was necessarily very heavy asthe outer supporting member was usually cast of metal, while the bowl or hopper was made of porcelain. This was satisfactory in the older style of railway coaches where the weight of the water closet was not considered as being excessive anddid not materially afiect the speed and operation of the train. But in the present era, the railways have come to the conclusion that weight is a necessary factor to be considered, andthey have increased the speed and efiiciency of operation by lightening the trains, streamlining, and the like, and the weight of water closets has become an important item. The same factors obtain in the modern busses and trailers. Therefore, the instant invention contemplates the provision of water closets that are much lighter in construction, without sacrificing any ofv the important features of the prior art water closets.

Another important, object of the invention is the provision of such a light weight water closet in which thesame operating mechanism heretofore employed may be ,interchangeably'used.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, when taken in connection with the accompanying drawings, disclosesa preferred embodiment thereof.

In the drawings:

Figure 1 is a side elevational view of a water closet embodying the features of the invention; and

Fig. 2 is a vertical sectional view taken substantially on line 22 in Fig. 1.

Referring more particularly to the drawings, reference numeral H indicates in general a water closet or hopper comprising a bowl l2 and a stand or supporting portion l3 formed integrally therewith. By making the bowl and stand in one piece,

a very much lighter'w'ater closet results, without sacrificing any of the advantages of the prior art 5 water closets of this type. The bowl l2 and stand 53 are preferably molded from vitreous china, porcelain, or the like, although a thin metal casting may be employed.

A dump pan l4 normally closes the lower end of the bowl [2, as shown in Fig. 2, and is fixedly mounted on a transverse shaft l5 extending through and suitably journaled in the side walls of the stand portion l3 of the water closetil. The dump pan M and operating mechanism therefor will be briefly described herein, a more complete and detailed description of similar mechanism being given in United States Letters Patent Nos. 1,831,528; 1,845,252; 1,898,656; 1,898,657, and,1,992,653

An arm l6, fixedly secured to the shaft !5 at one end, isprovided with a pin l1 extending into a slot I8 which is provided in the lower portion of a link l9. The opposite end of the shaft I5 is equipped with an arm 2| carrying at its free end a counterweight 22 for normally holding the. dump pan It in closed position, as shown in Fig. 2.

The upper end of the link I9 is pivotally connected at 23 with a lever 24 having a handle 25 at one end and being connected at the other or fulcrum end with afiushing valve 26 of any preferred or desired construction, so that upon raising the lever 24, the movementof the dump pan M to open position is initiated while at the same time the flushing valve 28 is set in operation in order to thoroughly flush the interior of the bowl I 2.

Within the lowerend of the stand portion l3 directly below the bowl l2 and dump pan I4 is positioned a funnel-shaped, downwardly extending member 21 (Fig 2). The member 2'! is d tachably associated with the stand I5 so that the dump pan I 4 is easily accessible, either for repairs or removal. 'I'he upper flaring edge 28 of the member 21 abuts against a shoulder 29 formed within the interior of the stand portion i3. A non-soluble cement or putty 3! is used to make the joint between theupper end of the member 2! and the shoulder 29 water tight and prevent any seepage therethrough. Cast integrally with the member 21, near its converging end, is an outwardly disposed, annular flange 32. A rubber gasket 33 is inserted between the flange, 32 and the lower portion of the stand l3 to provide a 5 cushion-like mounting for the water closet II when the same is installed in a railway coach or other moving vehicle. A number of bolts 34 secure the fiange 32 and the stand I3 together so that the closet ll may be moved as a single unit. The entire unit may be fastened to the floor or other supporting means by suitable bolts 35.

A pair of oppositely disposed bearing members 36 and 31 are cast integrally with the member 21. A shaft 38, journaled in the bearing 36, carries an arm 39 fixed thereto at one end, and an arm 4| loosely mounted thereon, the latter having a bifurcated end 42 which loosely supportsit on the shaft 38. The other end of the arm 4| is yieldingly connected to the fixed arm 39 by means of a coiled tensioned spring 43. A pin 44 projecting laterally from the arm 4| between its ends serves as a pivotal support for a lever 45 which carries a weight 46 equipped at its lower portion with a knob 41 of rubber, or other suitable shock absorbing material.

Afinger 48 projecting upwardly from the lever 45 supports at its free end an adjusting element or screw 49 extending through a tapped opening of the finger 48 against a lug or abutment which projects laterally from the arm 39. The screw 49 is held in adjusted position relatively to the finger 48 by means of a nut 52. I

Extending inwardly from the weight 46 is a pin 53 which is adapted to travel in a slot 54 formed in a link 55 which is pivotally secured at 56 to a segment lever arm 51. The outer periphery of the segment lever arm 51 is in the shape of an arc of a circle having its center at the center of the shaft I5. The segment lever arm 51 is adapted to come in contact with a small roller 58 (Fig. 2) attached to the fixed arm 39, and is fixedly mounted to the shaft l5by means of a coupling lever 59.

Journaled in the bearing which has fastened to it at its outer end an arm 62, which in turn is fastened to a weight 63 similar in size to the weight 46. Fastened to the inner end of the shaft 6| and. disposed interiorly of the stand portion 13 is a downwardly extending arm 64, and a corresponding arm 65 is also fastened to the interior end of the shaft 38. The lower ends of the arms and 65 are in turn fastened to a draft member or sealing plate 66 which is adapted to close the lower open end of the member 21.

The draft plate 66 is normally held in a partially open position so as to prevent freezing thereof to the lower end of the member 21 when the closet H is used in cold weather. However,

when the lever 25 and the lever arm 24 is pressed downwardly, the segment lever 51 comes into contact with the roller 56. ment of the segment lever 51 causes a movement of the arm 45, and this in turn causes the shafts 38 and El to rotate and thus close thedraft plate 66. Upon the continued downward movement of the-lever 24 the dump pan l4 is moved away from the opening in the bowl l2. Upon return to normal position of the lever 24 the dump pan l4 again closes the opening in the bowl I2 and the draft plate 66 opens to allow the refuse to be emptied.

By casting the bowl l2 and stand portion l3 integrally, a much lighter structure is provided 31- 15 a shaft/ 6! The initial movethan those employing a separate bowl and stand, as shown in the patents above referred to. The necessity for additional securing means, such as is disclosed in U. S. Letters Patent No. 1,711,635, is also eliminated, while permitting ready removal of the water closet for cleaning or repair service. The light weight construction thus provided, together with the novel cushioned mounting therefor results in a water closet which is particularly adapted for. use in vehicles, especially those in which weightis of primary importance.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
